sparc,sparc64: unify Makefile
To unify Makefile for sparc and sparc64 a few other steps was needed: 1) separate defconfig files for sparc and sparc64 is required, so locate these in arch/sparc/configs 2) removoval of hack in toplevel Makefile to deal with that headers was in a separate directory compared to the rest The unification of the Makefile required usage of several foo-$(CONFIG_SPARCnn) += due to a few directories pending unification. This will be cleaned up when we unify the remaining directories. Included in this patch are the deletion of a few files in sparc64 as they are no longer needed: Makefile + Kconfig. arch/sparc64/ will after this patch is applied only have four directories (prom, lib, kernel, boot) Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.
